Smash Bros+Rabbids Kingdom Battle

(This fanfiction is being redone in a whole new way, so you can read this "beta" version at your own risk. Don't get upset at me when you cringe horribly. The remastered variation is out now on my new account, PixelRolls, so you can go give it a read if you don't really have anything else to read...)

In a futuristic world, a young inventor and avid Super Smash Bros fan, with the help of her robot assistant Beep-0, has invented a device known as the SupaMerge helmet, which can merge any two objects together into a single entity. She invented it with the intention to solve an energy crisis, but the device has a problem with overheating. But when the inventor leaves the room, a group of Rabbids arrive in their Time Washing Machine, one of which puts the SupaMerge helmet on and starts causing chaos. While having fun with the helmet, it accidentally hits the Time Washing Machine and causes a malfunction, sucking the Rabbids and Beep-0 into an interdimensional vortex. At that time, another vortex appears In the World of Trophies and above the Mushroom Kingdom and sucks up everyone, including Mario and his friends. As both Mario's friends and the Rabbids are thrown across the Mushroom Kingdom, Beep-0 discovers that the SupaMerge helmet has merged itself with the Rabbid wearing it, who starts causing more chaos by merging more things together. Mario must work together with his fellow fighters and Rabbid counterparts of them in order to save the Mushroom Kingdom, and possibly, the World.
